There are actually two processes for the manufacture of cardboard masks, used for fancy dress,

viz:

a. The cardboard moulded by any process (manual or mechanical process) allows of obtaining a mask in relief, which is subsequently painted and decorated with a paint-brush, an air gun or by any other means.

27. The cardboard printed and cut out flatwise, and in which openings for the eyes, the nose and sometimes the mouth are provided, allows of obtaining a mask without reliefs.

The object of the present invention is to provide a manufacturing process allowing, for obtaining masks in relief, to use cardboards printed fiatwise and which, consequently, can be rapidly and economically coloured.

The invention also concerns the new commercial products which can be obtained by this manufacturing process.

In the accompanying drawings and by way of example:

Fig. 1 is a view of the cut out blank ready to be stuck.

Fig. 2 is a vertical section of the die and of the punch for embossing the stuck blank.

Fig. 3 shows the position of the blank before embossing.

Figs. 4 and 5 are respectively a front view and a side view of a finished mask.

Fig. 6 is a view of the cut out blank according to a modification of the invention.

Fig. '7 shows this blank placed on the formingblock, ready for embossing, and

Fig. 8 illustrates the mask obtained by means of the blank shown in Fig. 6.

As above characterized, the object of the invention is to provide a mask moulded in relief from a blank printed flatwise. For that purpose, this blank I is cut out so as to provide a notch 2, of approximately triangular shape. The printing of the coloured design is eiiected in such a manner that the two parts 3 which surround the notch exactly join each other when both edges of the latter are applied one on the other. From this fact, the blank assumes the shape of a conical surface (Fig. 3).

The blank cut out in the cardboard thus printed is moistened, then stamped between two male and female forming-blocks 4, 5, care being taken to ensure the registration of this blank by causing two guide rods 1 to enter holes 6 formed at the place of the eyes, which guide rods are pro- 5 vided for that purpose with moulding members. Owing to the clamping action, both edges of the notch move towards each other and are superposed. As they have previously been coated with glue, these edges immediately adhere, the drying 10 being produced nearly instantaneously owing to the heat to which the forming-blocks are subjected by means of heating perforated pipes 8. Masks in relief are thus obtained, which are terminated when they issue from the moulds and 15 are ready for sale (Figs. 4 and 5).

Figs. 6, '7 and 8 illustrate a modification of the invention according to which the blank is provided at its edge, on both sides of the notch 2, with lugs A, A which come one on the other 20 when the edges of the notch are moved towards each other and superposed. Both lugs A, A are then secured one on the other by means of a fastener B so as to hold the blank in the shape of a cone, this facilitating its placing in position on the embossing block 4 (Fig. 7) After embossing, the lugs A, A are finally cut off from the terminated mask (Fig. 8).

Modifications may be made in the forms of carrying this process into practice without depart- 30 ing thereby from the scope of the present invention. In particular, the notch formed in the fiat blank can vary in width and in shape according to the depth and to the relief of the mask to be obtained. The same is true concerning the shape 35 of the lines constituting the edges of this notch.

I claim:

A process for the manufacture of masks in relief, consisting in forming the mask in outline shape and painted in accordance with mask re- 40 quirements, with the mask divided on a re-entrant angle extending from the lower central edge and terminating approximately on the transverse central line, and then molding the mask in relief with the edges forming the division overlapping and 5 secured together.
